Generate a full detail guide to essential beginner gardening tools. The guide must be simple and clear. For each of the following 7 tools (Hand Trowel, Pruning Shears, Garden Fork, Shovel, Rake, Hoe, Watering Can/Hose), provide: 1. A clear description of the tool. 2. Its primary use in the garden. 3. A tip on what to look for when buying one. 4. A section on proper care and maintenance for the tools. The goal is to create a definitive 'first toolkit' guide.
